Duetto Ultra-mini earbuds


Initially used at a professional level as a concert monitor for musicians, in-ear headphones have now become a mass product thanks to the diffusion of listening on the move offering the advantages of portability and lightness as well as the passive soundproofing of the external environment. Always evolving to meet industry needs, K-array has developed the Duetto, ultra-mini high-quality aluminum alloy earbuds.

Duetto High-quality Design Designed by engineers with over 25 years of experience in the world of live professional audio, the Duetto, in its infinite compactness, is equipped with full-range transducers capable of reproducing the whole frequency range from 5 Hz to 23 kHz ensuring the highest quality and fidelity of audio reproduction. In addition to incredible sound quality, luxury materials, like an easy-to-coil Kevlar cable and durable aluminum alloy ear buds, offer extra refinement and comfort for all music lovers.

Duetto Performance Unlike the classic earphones that are included with the purchase of most smartphones and mp3 players which do not enter the ear canal and instead sit at the base, the Duetto in-ear headphones penetrate the external auditory canal and transfer the sound pressure towards the eardrum.

The 6mm Neodymium transducer provides an ideal acoustic compression with a loud full-bodied sound output, isolating the eardrum and sealing off outside noise from the mutual relationship that is created between the earphone and the eardrum - exactly how our loudspeakers function where the sound box is separated from the external environment.

And similar to speaker’s reflex port that resonates air based on the movement of the woofer, the earbuds are equipped with a micro hole that increases the efficiency of the transducer at low frequencies, contradicting audiophiles who suggest that in-ear headphones are too small to provide the sound depth and quality to enjoy music.

Duetto Accessories The Duetto comes with three types of ear tips in silicon and memory foam to provide comfort and circumvent slippage from the ear canal. Other accessories include a two-prong plane adapter, a 2-in-1 3.5 mm jack for multi-listening and a genuine leather carrying case. With such efficiency, sound fidelity, compactness and quality materials, the Duetto are the smallest ear buds on the market with these performance characteristics which remain consistent with K-array’s quality standards.
